My lab is focused on two projects:Research in my lab is focused on regulation of gene expression by specific transcription factors during brain development, the implication of their loss on brain function and the mechanism(s) underlying the manifestation of neurological disorders. Specifically, my lab is interested in the molecular and cellular mechanism underlying Rett syndrome and other autism spectrum disorders. RTT is caused by sporadic mutations in the methyl-CpG binding protein 2 gene, Mecp2. Although MeCP2 is a global transcription factor, its loss affects preferentially the central nervous system (CNS). My lab studies the molecular mechanism(s) by which the loss of MeCP2functionmanifest as neurological symptoms at specific developmental stage, and the non-cell autonomous effect of glia in manifestation and rescue of RTT. The other research interest of my lab focuses on identifying the roles of the transcriptional repressor REST in CNS development in health and disease. REST is a master regulator of a large network of genes involved in acquisition of neural fate and its dysregulation has been implicated in several neurological disorders, as well as cancer. My lab characterizes the roles of the REST repressor complex in maintaining stem cell identity and progressing into different neural lineages in vivo and ex-vivo. Both projects involve multidisciplinary approaches including molecular, cellular and behavioral approaches.
